1 Claim.

This invention relates to adjustable paper stop devices for accounting machines having a traveling carriage and a roller platen. The device is adapted to be used as a stop for paper fed downwardly into the machine from in front of the platen.

The present construction is an improvement over the construction disclosed in my co-pending application Serial No. 92,164, filed July 23,

The principal objects of the present invention are to make the adjusting knob easier to turn; to insure synchronous advance and retraction of the paper stops; and to make it easier for the operator to adjust the paper stops to a predetermined position.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claim, and a preferred embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

In the drawings:

Figure 1 is a perspective of an accounting machine equipped with the present invention,

Figure 2 is a perspective showing the invention,

Figure 3 is a right side elevation of the means for driving the index disc,

Figure 4 is a front sectional elevation of one of the tape reels.

Figure 5 is a perspective of one of the tape reels with certain. parts broken away, and

Figure 6 is a right side elevation of the parts shown in Figure 5.

In the drawings, an accounting machine I is provided with the customary traveling carriage 2 having a roller platen 3 for supporting paper to be printed upon by the customary type bars. The paper 4 (Figure 2) is inserted by the operator between platen 3 and a guide plate 5. A pair ,of adjustable stops 6 are provided to stop the paper when the operator has inserted it the desired distance. These stops 6 are adjusted forwardly and rearwardly of the machine by similar tapes I wound upon and operated by two reels 8, one of which is shown in Figure 5. The reels are 5 identical in construction, so that a description of one will suffice for both.

The reel 8 (Figure 4) is composed of two flanged discs ll situated on opposite sides of a gear 12, the three parts being riveted together 55 at I3. The reel assembly is mounted on a shoulj The teeth on gear [2 are of sufiicient length to allow the entire tape to be wound thereon (see Figure 4) without extending beyond the ends of the teeth. The apertures in tape I are spaced progressively farther apart, toward the front end 10 of the tape, to compensate for the constantly increasing diameter of the reel as the tape is wound thereon. By the provision of these teeth, when shaft I5 is rotated, tape 1 is positively moved .in either'direction. Upper and lower 15 guide strips 2i and 22 (Figure 6) embrace tape 1 from its upper and lower sides to prevent it from buckling when shaft l5 moves the tape forward. A grooved roller 23 (Figure 4) loosely mounted on a rod 24 is provided to prevent the 20 tape from being forced off the teeth of gear l2 when the tape is moved forward. Roller 23 and rod 24 are carried in! a bracket 25 (Figures 5 and 6) pivoted on a rod 26. A depending arm 21.

on the bracket is pulled forwardly by a spring 28 25 to press roller 23 against the upper surface of the tape 1.

It is apparent that since the two reels 8 are identical, and are both secured to shaft 15, that after the paper stops 6 (Figure 2) are initially 30 placed in alignment, adjustment of stops 6 by rotation of knob l8 movesstops 6 forward or rearward equal extents.

A gear 3| (Figures 2 and 3) is secured to shaft l5 and meshes with a gear 32 secured to a 35 flanged disc 33. Gear 32 and disc 33 are rotatable on a stud 34 secured in the carriage side wall 35. A pointer 36 also is secured to side wall 35 and overlies an index provided on the flange of disc 33. The index may be arranged to correspond with the spaces on the printed forms adapted for use in the machine.

With the above described mechanism, when an operator Wishes to insert a sheet of paper from the front of the platen and accurately align the paper so that the printing Will be horizontal on the sheet and on the proper line, it is only necessary for him to turn knob I8 until the appropriate number on the index is located adjacent the pointer 36, and to then insert the paper in the machine until he feels the paper encounter the stops 6.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein disclosed for it is susceptible of embodiment in various forms all coming within the scope of the claim which follows.

What is claimed is:

. In a machine of the class described, an adjustable paper stop device including a paper stop, a flexible apertured tape connected thereto, a

toothed reel on which the tape is wound, retaining means for holding the tape in engagement with the teeth at the point where the tape leaves the reel, and means for moving the retaining means toward the tape and reel to keep the retaining means in contact with the tape as the latter is unwound from the reel.
